Ring Roller Mill

The ultra-fine ring roller mill is a type of dry roller mill for ultra-fine powder production equipment. It is developed by our company through independent innovation based on the advantages and disadvantages of roller mills at home and abroad. It adopts the principle of fluid mechanics and can grind to a fineness ranging from 3-35um. It has the characteristics of good performance, high efficiency, small footprint, easy Installation, etc. The product has good particle size index and stable performance.

Ring Roller Mill

How It Works

Technical breakdown of the core processes and technology behind Ring Roller Mill.

The ring roller mill crushes materials through the combined principles of impact, extrusion, and grinding. The grinding ring bracket is designed with a large clearance between the grinding ring and the pin shaft. As material passes through the gap between the grinding rings, it is impacted, squeezed, and ground by the rings, resulting in effective size reduction.

After crushing, the material falls under gravity onto the feed tray and is then carried by airflow into the classification chamber. Qualified fine particles are conveyed by the classifier rotor into the collection system, while coarser particles are thrown against the split ring wall and returned to the crushing chamber for re-grinding.

In the case of a double-layer grinding machine, the material undergoes secondary grinding as it passes through the gap between the second set of grinding rings, ensuring further refinement.

Performance and Features

Uncompromising performance and innovative design, optimized for high-efficiency production and durability.

Multi-Layer Design for Fine Grinding

Multi-layer sub-assembly structure ensures progressive crushing through impact and rolling, achieving thorough grinding and ultra-fine fineness.

High Efficiency & Low Energy Consumption

Enhanced by high-pressure centrifugal force, rolling force is increased by 30–40%, doubling production efficiency compared to traditional mills.

High Capacity for Large-Batch Production

Capable of outputting over 1 ton per hour (e.g., calcium carbonate at 10μm), effectively shortening production cycles for large-scale needs.

Controllable Fineness & Eco-Friendly

D97 reaches 3–35μm with stepless speed regulation. All fine powder is fully recovered, ensuring zero dust pollution and flexible adjustment.
